Specification of Letters Patent.

Patented July 2'7, 1909.

Application filed August 20, 1908. Serial No. 449,455.

To (all! whom it may concern:

lie it known that 1, JOHN Enwann GLou-khan, citizen of the United States. residing at littsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Air Cooling i ipparatus, of which the following is a specification.

My invention pertains to air cooling apparatus for use in refrigerators.cold storage apartments and the like; and it contemplates the provision (it-a simple and durable air cooling apparatus, constructed with a view of being easily kept; in a sanitary condition; of maintaining an adequate circulation of air in proximity to the cooling means employed. and of preventing the dissipatioi'i of cold except tothe current of air while the same is en. main to the chamber in which products to bepreservcd are stored.

With the .loregoinsr in view the invention will be fully understood from the following description and claims when the same are read in connection with the drawings. accompanying and forming part: of this speliititration, in which:

l' i ure 1 is a side elevation ot' the air cooling apparatus constituting the best practical enibmliment of my invention of which i; am aware. Fig. 2 is a plan view of the same. Fig. 1-3 is a transverse section taken through my novel ammratus in the plane-indicated by the line 3-3 of l igg's. l and 2. and illustrating the apparatus as properly positioned in the casing of a refrigerator or the like. Fig. 3" is a detail section showing the ar raugement of the metallic portions [1 oi the conduit walls on the intermediate tin'ibers A.

Referring by letter to the said drawings: A A are timbers adapted to be fixed transversely in a refrigerator casing between pposi'te walls B of the casing, as shown in Fi e".

.3. The said timbers A are separated by intervening spaces, Fig. l, and arranged on and connected to the timbers is a pan C which is formed entirely of suitable metal. this in order to take advantage of the good heat-ctmductor quality of metal to cool air incidental tothe pass; go of the same through the pan. As clearly shown. the pan 7 comprises a rectangular trame (z. disposed above the timbers A. and conduits 7) arranged intermediate ot' the timbers A and fixed with respect to the said timbers and also with respect to the before mentioned open, rectangular frame a. Any desired number of con? the conduits 1') have side walls f, and that the outer side walls ot the end conduits have flanges g which rest. on and cover the end i timbers A; while the other side walls of the conduits are connected by horizontal metallic. portions h which rest on and cover the inttrmediate timbers A. Fig. 3. it will be t'urthtn noticed by reference, to the drawings. and particularly to Fig. 3 thereof, that the side bar of the frame a above the bottom portions 1/ ot the conduits F) is provided with downwardly and inwardly inclined flanges /7.

(En the horizontal portions 9 and h of the pan C is arranged and permanently secured a. frame I), of metal, which has for its ofiice to support the means employed to cool air incidental to the passage of the latter through the apparatus; and at this point I would have it. understood that the scheme of my invention contemplates cooling the air which rises at the side N0. 1 in Fig. 3, and thenpermittingthe cold and heavy arr to descend through the frame D and the COIltlUlts Z) and to pass back to the storage chamber through the spaces at the side No. 2 of the apparatus. lee is employed as the agent for cooling the air incidental to its passage through my novel apparatus in the manner described, andl ifiake the conduits serve the additional function of carrying the water from the melting ice to a trough E which arranged to receive water from the-flanges o'r skirts c and is provided with a conduit y, designed to carry such water outside of the refrigerator or the like.

In taking the. course described through my novel apparatus-it. will be noted that the-air comes into. direct contact with the metal of which the pan C is formed. and by virtue of the metal being algood conductor of heat it.

will be manifest that the air will be quickly cooled. It will also be noted by reference to Fig. 3 that the under sides of the bottom portions d andc, ot the conduits Z) are cov-' .ercd and insulated by horizontal strips d,

of wood, and inclined strips also of Wood,

this being advantageous inasmuch as it prerents cooling of the air as the latter ascends against the cooling apparatus; and it will further be noted in this connection that the inclination of the bottom portions 0 of the conduits and the corresponding inclination of the non-conducting strips 0 serves to guide or deflect. the rising warm air to the ide No. 1 of the ap iaratus, and in that. way contributes to the maintenance of anadequatc circulation of air through the apparatus.

For the purpose of properly holding ice 1 provide the frame I) with longitudinally dispo-zed seats G arranged side by side, as best illustrated in Fi and 3, and I also provide longitudinal ice-supporting bars H which are arranged in and are adapted to be removed one by one from the said seats (l.

'lhus it will be understood that when it is desired to clean the apparatus, each of the bars it may he removed independently of the others and after being cleaned may be quickly and easily replaced in position on the frame i); and it will also be understood that when all of the bars H are removed. ready access may be gained to all parts of the pan C and frame I) to facilitate the thorough cleaning thereof. The bars ll are of circular form in cross-section. and from this it follows that the liability of sediment adhering to the bars is reduced to a Illlflil'llllll'l; also. that the bars when removed from the apparatus are adapted to be thoroughly cicaned in an expeditious manner.

The grating formed by the frame I) and the bars it serves in combinatiai \vithan impcrforate side wall I. an open \Y rlli side wall J and an impert'orute back wall K, all of metal, to form an ice receptacle. The wall l is provided with an insulating backing l. of wood or oth r suitable material. and by reference to Figs. 1 to 9. it will be se n that the said wall i which arranged a the side No. l of the apparatus is prorided in it upper portion with openings L for the passage in warm air into the icerecptaclc. it will also be seen that because of the open work character of the wall 'J. the air is free. after passing through the ice, to take passage through the said wall J precedent to (,lcscendiu at the side .\'o. 2 of the apparatus.

My improvemrnts are arranged in a ret'rigeratu' casing between opposite walls thereof amt bctwccn the closed top of the casing and a provisionchamber indicated by X in Fig. From this it follows that air will risc from the provision chamber X at. thc side X -l of the apparatus. and then after de cending through the. openwork frame to the conduits Ii or else passing through the openwork side Walls of the apparatus, will descend in a cooled state at the side N1). 2 of the apparatus and pass back to the provision or storage chamber X.

I have entered into a detailed description of the constructioi'i and relative arrangement of the parts comprised in the illustrated embodiments of. my invention in order to impart a full, clear and exact understanding of the same. I do not desire, however, to be understood as confining myself to the said specilic' construction and relative arrangement of parts, inasmuch as in the future practice of my invention such changes or modifications maybe made as fairly fall within the scope of the invention as defined in the claims appended.

Having described my invention, What I claim and desire to secure by Letters-Patent, is:

1. The combination with spaced walls, of an air cooling apparatus arranged to atford aertical passages for air between its opposite sides and the said walls, and comprising a plurality of spaced supporting timbers ex tending between the walls, a pan suppvrted on said timbers amt having, in the spaces in- ;eriuialiate the timbers. transverse conduits, open at one side of the pan; the bottoms of the said conduits being inclined downwardly from the opp :site side. of the pan. and the said bottoms being insulated at their under s des. and being each provided. at the open end of its reslwctiic conduit. with. a depending flange. a trough disposed below and l rip ht angles to the timbers and p'isitioned i) receive water from the depending flanges ot the conduits. a grating supported on the pan and adapted to support ice, and an imperforute side wall. an impcrtorate rear wall. and an open-w )rh side wall, supported on the pan and serving in conjunction with the grate to form an icc receptacle, the said openuvork side wall being arranged adjacent the trough.

A grating for the purpose described. mprising end strips having lingitudinally disposed seats. of semicircular form in crossection-. at intervalsin their length, and longitudinal. metallic bars. of circular form in cross-section. arranged in said seats and removable individually fr an the same. and means for supporting the said st rips.

in testimony whereof I have hereunto set my hand in presence of two sul'iscribing witnesses.
